2010, 2011 to the irs. senator max baucus, michael bennett, al frank and chuck schumer, tom udall, they all signed these letters. is there any evidence that the letters influence those at the irs to go ahead and single out tea party groups, or conservative groups for special attention before granting them this tax-exempt status? >> so far there's no direct evidence, no. i can't imagine this issue won't come up with all the republicans asking questions tomorrow, and of course, next week. i can tell you that max baucus went on the senate floor yesterday and said yes, he wrote this letter, but he didn't mean for it just to be targeting conservative groups, he meant it to be something that would be scrutinized across the board. democrats, republicans, everybody. >> the inspector general's report said they had no evidence that outside influence outside of the irs influenced these individuals, these officials at the irs, who were doing what they were doing. we'll see what happens at that hearing. thanks very much, dana.
